So i’m making the upper torso of a 1:1 scale humanoid robot… Think Terminator. There are a few basic mistakes, such the the motor ordered for the rotation around Z is different than the website’s datasheet indicated.
Also because of the belt tension, the ABS is flexing too much making the teeth slip. I am working on a metal bracket that I can mill and screw on. Less than ideal, but plastic isn’t really meant to take this much force.
The upper arm is temporary as I am not 100pct happy with it.
Next step… rotary encoder housing for each axis.
